Activated alumina ball price of activated alumina purity alumina is a white amorphous powder, commonly known as bauxite, density 3.9-4.0g / cm3, melting point 2050 ℃, boiling point 2980 ℃ Jishou molecular sieve, sieve Lengshuijiang insoluble in water, aluminum main There α type and γ-type two variants, can be extracted from bauxite industry. Bauxite (?? Al2O3 H2O and Al2O3 3H2O) in primary aluminum naturally occurring mineral, the crushed impregnated with high temperature sodium hydroxide solution, sodium aluminate solution to get it; filtered to remove the residue, and the filtrate cooled and hydroxide aluminum crystals, after long stirring zixing molecular sieves, sodium aluminate solution is decomposed to precipitate aluminum hydroxide precipitate; separating the precipitate was washed Shanghai new molecular sieve Ltd. Thomas, who use HRTEM technology was first discovered in 1982, ZSM-5 / ZSM-11 2-phase co-crystals have been reported now synthesized SSZ-26 / SSZ-33, ZSM-34 (OFF / ERI), SSZ-36 (ITE / RTH), STF / SFF, SM-3, ZSM -20 and EMT / FAU and other two-phase co-crystalline molecular sieve [1-4]. Qi Xiaolan using fluoride -TEA composite template system, synthesized zeolite BEA - 2 Intergrowth mordenite zeolite field. Hongjiang molecular sieve, sieve, there is a new molecular sieves (View) by the Shanghai new molecular sieve Limited. Shanghai new molecular sieve Limited (www.molsionms.com) is a professional engaged in "molecular sieves" company. Since its inception, we adhere to the "good faith, sound management" approach, the courage to participate in healthy competition in the market, so that the "new" brand has a good reputation. We adhere to the "service first, customer first" principle, so that there is a new molecular sieve has won the public's trust of customers in a single substance, and establish a good corporate image.
